--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:9ace5d4dab2ab39072b0f07089621a823580f27c commit r12-8273-g9ace5d4dab2ab39072b0f07089621a823580f27c Author: Jason Merrill <ja...@redhat.com> Date: Tue Apr 26 00:19:40 2022 -0400 c++: pack init-capture of unresolved overload [PR102629] Here we were failing to diagnose that the initializer for the capture pack is an unresolved overload. It turns out that the reason we didn't recognize the deduction failure in do_auto_deduction was that the individual 'auto' in the expansion of the capture pack was still marked as a parameter pack, so we were deducing it to an empty pack instead of failing. PR c++/102629 gcc/cp/ChangeLog: * pt.cc (gen_elem_of_pack_expansion_instantiation): Clear TEMPLATE_TYPE_PARAMETER_PACK on auto. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/lambda-pack-init7.C: New test.
